Closing the viewer and restarting did not help. I cannot find any option to make them appear again: not in the viewer options, not in the calibre preferences. Issueing Ctrl-F didn't work anymore.
Beside re-installing, is there a simple cure for this?
Somehow you managed to lose/misplace the Search toolbar.
Note: you can drag the tool bar(s) using the ribbed 'handle' at the start to locations at the top or Left side and Calibre will leave them there.
